Overview
The LMX339AUD+T is a quad general-purpose low-voltage comparator manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1.8V to 5.5V and supports an automotive temperature range from -40°C to +125°C. The device features a 14-pin TSSOP package with open-drain outputs. Key electrical specifications include a maximum input offset voltage of 7mV at 5V, a typical supply current of 120µA at 2.7V and 300µA at 5V, and a propagation delay of 600ns maximum at 10mV overdrive.
Feature Summary
- Drop-in pin-for-pin compatible replacement for LMV339/LMV393 series
- Internal hysteresis available in H-series variants for noise immunity
- Designed using advanced submicron CMOS technology
- Wide operating temperature range suitable for automotive applications
Applications
- Mobile Communications
- Automotive Applications
- Battery-Powered Electronics
- General-Purpose Portable Devices
Procurement Notes
Verify the specific suffix 'AUD' corresponds to the 14-pin TSSOP package and standard (non-hysteresis) variant as documented in the ordering information table. Confirm RoHS compliance status indicated by the '+' symbol. Check component availability as product lifecycle status may vary; consult official manufacturer channels for current production status and lead times.
Selection Notes
Select this component when a quad comparator configuration is required in a compact surface-mount package. Ensure the design utilizes external pull-up resistors due to the open-drain output structure. Consider the LMX339H variant if internal hysteresis is needed to prevent oscillation on slow-moving signals without adding external feedback components.
Part Context
This part belongs to the LMX331/LMX393/LMX339 family of general-purpose, low-voltage comparators. These devices are designed to replace older industry standards like the LM339 while offering improved performance characteristics such as lower power consumption and smaller footprint through modern CMOS fabrication techniques.
Replacement Considerations
The datasheet identifies the LMX339AUD+T as a drop-in, pin-for-pin-compatible replacement for the LMV339.
